SH EET- M ETAL LATCH-BO LT.

SPECIFICATION forming part of Letters Patent No. 479,582, dated July 26,1892.

Application filed February 1, 1892. Serial No. 419,856. (No model.)

To all whom it may concern.-

Be it known that I, HOWARD D. ALLEN, a citizen'ot' the United States,residing at New, Britain, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements in SheetMetal Latch-Bolts, of which the following is a specification.

My invention relates to improvements in sheet-metal latch-bolts; and theobjects of my improvements are simplicity and cheapness of constructionand the production of a superior article.

In the accompanying drawings, Figure 1 is an edge View of my latch-bolt.Fig. 2 is an elevation thereof, showing the side having the beveledface. Fig. 3 is a central longitudinal section of the same. Fig. 4 is alike view of the main portion of the same. Fig. 5 is a plan view of theblank from which I form the main portion of my latch-bolt, and Fig. 6 isa perspective view of the angular finishing-piece for the head of mylatch-bolt.

The head of the finished latch-bolt is of the ordinary form, having thestraight holdingface '7 and wiping beveled face 8, while the body orback for some distance inwardly from the head has a side flange 9 ateach edge. The shank or tail 10 may be of any ordinary form and providedwith any suitable lug, as at 11, fora spring to press against or otheruse, according to the kind of latch in which the bolt is to be used. Myinvention relates to the head end and adjacentbody of the latch-boltthatis to say, the end having the beveled wiping-face 8. I construct themain portion of this end, together with the shank or tail 10, from aflat sheet-metal blank, having side wings 12 and connected flanges 9,while the middle portion of the blank forms the back on which is thestraight holding-face 7 of the finished latch-bolt. I- perforate theblank through the back at a point opposite the inner ends of wings 12,as shown in Fig. 5. I bevel the outer corners of the side wings 12 onsubstantially the desired bevel for the beveled wiping-face 8, exceptingas I leave small corners 14 in the blank near the bending-lines, asshown in Fig. 5. The side wings 12 and connected flanges 9 are bent upon the lines 15, Fig. 5, into substantially the form shown in thepreceding figures. The outer edge of the metal between the side wings isthen cut out a little and beveled off, as shown at 16 in Fig. 4, thebevel thereof being back from the beveled edge of the side wings adistance about equal to the thickness of metal employed for making thelatch. I also form of sheet metal the angular finishingpiece, Fig. 6,the same being of a width that will fill the space between the sidewings 12. This piece is provided with a tenon 17, designed to fit thehole in the back of the latchbolt, into which it is riveted, the metalcontiguous with said tenon constituting the square end 13 of thelatch-bolt head, as best shown in Fig. 3.. The slanting arm of theangular finishing-piece, which constitutes the main portion of thebeveled face 8, lies in between the side wings near their beveled edges,so as to complete that end of the latch-bolt head. After thus firmlysecuring the angular finishing-piece in place the latch-bolt may befinished by grinding or polishing, thereby removing all surplus metalthat may remain of the corners 14 of the blank, Fig.5, and otherwiseshaping the boltas, for instance, squaring the nose and rounding off thebeveled face, (be.

By leaving the corners 14 in the blank, Fig. 5, I insure full corners atthe nose of the latch-bolt after bending up the side wings. Thelatch-bolt is easily formed of sheet metal, whereby it can be producedat a small cost. It is strong and efficient and presents a neatappearance.

I claim as my invention The herein-described latch-bolt, consisting of amain portion having side wings 12, bent up from a connected back, and anangular finishing-piece set in between said wings and secured to saidback, substantially as described, and for the purpose specified.
